摘要

为满足第5代移动通信技术越来越高的性能需求，设计了一种基于基片集成波导(Substrate Integrated Waveguide，SIW)谐振腔的高增益大带宽的可重构天线。通过矩形贴片和谐振腔的耦合，并在主单元两侧布置寄生单元，使天线的回波损耗

≤−10 dB的工作带宽达到10.7%(3.36～3.74 GHz)。工作区间内最大增益达到7.78 dBi。与其他同类天线产品相比，该天线可以减少使用2/3的移相器，并且其使用FR-4材料，具有较大的成本优势。

Abstract

In order to meet the high-speed working requirements of the fifth-generation mobile communication

a high gain antenna for 5G millimeter wave based on SIW is proposed. Through the coupling between the rectangular patch and the resonant cavity

and arranging parasitic units on both sides of the main unit

the working bandwidth of the antenna (

≤−10 dB) reaches 10.7% (3.36~3.74 GHz) . The maximum gain in the working range reaches 7.78 dBi. Compared with other similar antenna

the proposed antenna can reduce 2/3 of the phase shifter and it uses Fr-4 material

which is of greater cost advantage.
